AUXILIARY WINDQW SILL.

Specification of Letters Patent.

Patented May 16, 1922.

Application filed Gctober 1, 1921. Serial No. 5 4,555.

To all whom it may concern:

Be it known that L'IIAROLD JonNsoN, a citizen of the United States,residing at 170 Eighty-fourth Street, Brooklyn, in the county of Queensand State of New York, have invented. certain new and usefulImprovements in Auxiliary \Vindow sills of which the following '-is aclear and exact specification, reference being had to the accompanyingdrawings, which form a part of this specification.

This invention relates to removable, window-sill extension means and myimprovements are directed to the employment of a board, serviceable asan auxiliary sill, for seating and other purposes and provided withmeans whereby it may be removably secured and locked in position foruse, to support with safety the weights to be imposed thereon.

T he sills of windows being too narrow to seat with comfort and safetyaperson engaged in cleaning the outer surface of a window,-1 have devisedwhat 1 term an auxiliary sill, which can be easily attached to the usualsill, to afiord an ample outward seating surface whereon a personengaged in window cleaning or other duties may sit or stand with comfortand safety because the width of the seat is suflicient to obviate theneed of crowding in toward the window to prevent falling.

Since facility in adjusting such a device for service, and perfectsecurity of its engagement arc essentials, my invention also includesthe provision of slotted straps extending from the seat, which may becaught upon lixed headed bolts on the permanent silt, to positively lockthe seat thereto as suspended by stout cables from the window casing.

ther features and advantages of my invention will hereinafter appear.

In the drawing:

Figure 1 is a side elevation of my invention showing it applied to awindow.

Fig. 2 is an enlarged, sectional view, showing the manner of engagingthe locking ele ments, and

Fig. 3 is a top plan View of the device.

In said figures let 1 indicate a window casing and 2 the sill thereof.As permanent fixtures eyebolts 3 are secured in the casing, at each sideof the window to be served, and staples 4 are secured in the sill, inspaced relation, for a inafter.

My improved seat or auxiliary sill consists of a board 5, of suitablewidth and length, and of substantial thickness. A pair of straps 6, 6,are shown as secured by screws 7 to the base of board 5, being shapedforwardly at right angles to lie against the front edge of the board,and further, each having the bend 8 whereby their forward ends 9 aredirected upwardly and inwardly. The rear ends 10 of straps 6, 6, extendout fron the base of board 5 with a slight upward curvature. Shorterlength straps 11, 11 lie between the straps 6 and the board, in recessesprovided therefor in the base of the board, and are also secured theretoby the screws 7, these straps being shaped rearwardly at right angles tolie against the inner edge of the board, and eachhaving their rear ends12 directed upwardly and inwardly.

Thus the strap ends 9 and 12 are in converged relation and they haveeyelets 13 to receive respectively the hooked ends 14. if an angular,yoke-like rod 15, whose apex is engaged by a chain 16, whose upper end,having a. hook 17, can engage an eyebolt 8. Thus a pair of chains 16 androds 15 serve in conjunction with the eyebolts 3 as the suspension meansfor the board 5. It will be appreciated that the strength of theseelements is gauged to supply'an ample factor of safety support.

Furthermore, locking means are provided whereby the board 5 is connectedto the sill in such manner that it will not become accidentally detachedtherefrom, while at the same time being capable of easy adjustment toits operative position, and. of ready removal therefrom.

These locking means consist ofholes 18 formed in the strap ends 10, andslots 19 continuing forwardly from the holes, the diameter of the holespermitting them to receive the heads of bolts 1, while the slots are ofa width capable only of receiving the shanks of the staples. Therefore,in fitting the board 5 to a sill it is first inclined, in the mannershown in Fig. 2 to fit the holes 18 over the staple heads, and then ispushed inwardly and brought to a horizontal position causing the slots19 to slide upon the bolts and lock the strap ends 10 under the stapleheads.

The board 5, supported and locked in posipurpose to be describedheretion in the manner described, may be used as a seat for windowcleaners; a standing base for a person engaged in painting the windowframe and sash; or a sup'port'lor flowers or other objects, besideshaving other uses which will occur to the housewife.

Variations within the spirit and scope of my invention are equallycomprehended by the foregoing disclosure.
